3 Claims. (Cl. 129-1) This invention relates to binders and more particularly i to loose-leaf post binders for perforated paper sheets,

pamphlets and the like which may be frequently referred t0.

An object of the invention is to provide a binder adapted to hold a multiple of perforated paper sheets, pamphlets and the like for pivotal mounting in connection with my improved book stand, an application for patent on which was-tiled July 2l, 1926, Serial No. 124,011, which matured into a patent issued October 9, 1928, numbered 1,687,443. The book stand embodies the following three elements: a casing, a binder partially concealed in the casing and means pivotally connecting the binder inter'- mediate the ends thereof to said casing for supporting and permitting said binder to swing around said pivot outside of said casing in position for use.

A further object of this invention is to provide a binder of durable construction primarily adapted to withstand rough usage at the hands of the public and, also, in the field to afford means for ready replacement of parts damaged in use.

This invention lalso relates to my application for a patent on a binder led April 23, 1929, Serial No. 357,551, which matured into a patent issued June 24, 1930, numbered 1,767,978, and to my copending application for a patent on a binder filed November 5, 1948, Serial No. 58,425 which matured into United States Letters Patent No. 2,617,422 dated November 11, 1952. It is distinguished from the latter application in that it concerns itself with the handling of perforated loose paper sheets or pamphlets as contrasted with bound books such as telephone directories and the like. It includes improved construction, improved means for removably holding loose paper sheets, pamphlets and the like and improved means for locking the parts in operative connection.

This invention further relates to my copending application for a patent on a binder tiled February 23, 1949, Serial No. 77,959, now abandoned. Compared therewith it includes improved construction by eliminating the retaining studs and latching member and employing in their stead a part of the existing book coupling means of the first above mentioned copending application, Serial No. 58,425, forl locking the post-carrying unit in operative engagement.

With these and other objects in view, the invention consists in certain novel features of construction and combination and arrangement of parts, which will be more fully hereinafter described and pointed out in the claims.

Referring to the accompanying drawings by numerals, the binder is provided with a rigid backbone member of any desired material as, for example, a metal channelshaped section, preferably of polished stainless steel, comprs'ing a lat back plate 1 formed with perpendicular side walls 2 as illustrated in Fig. 3. As shown in Fig. 2 the back plate is formed at one end with a perpendicular end wall 3 extending beyond the side walls and which is pro vided with an offset 4 and an extension which is formed at its free end to provide a cylinder 5. As illustrated in Fig. l, the cylinder is provided with a series of slots 6. Positioned for reciprocal operation in the cylinder 5 and guided by the offset 4 is a U-shaped wire 7 which is formed with an offset extension at the free extremity of one leg and which is prevented from complete removal from the4 cylinder by contact witha retaining lip or detent formed 4 and a cylinder 5 at its free end, as shown in Fig. 2.

This cylinder is likewise provided with a series of corresponding slots 6 and a reciprocally operating U-shaped wire 7' which is retained in the same manner as above described.

Positioned in the side walls 2 of the back at any point intermediate the ends thereof are extruded apertures 9. The side walls are provided at their outer free edges with hinge knuckles 10 to which are attached the complementary hinge leaves 11 by means of the loose hinge pins 12. Attached to the hinge leaves 11 are the side covers 13 which may be made of any suitable material such as Bakelite, Masonite, liber or metal.

Nested in the back member 1 is an inner channel-shaped member 14 comprising a platform plate 15 formed with perpendicularside walls 16 in which are positioned apertures 17 intermediate the ends and aligned with the eX- truded apertures 9 of the back member as shown in Fig. 3. The sidewalls are provided at their outer free edges with inwardly projecting stiifening flanges 18 as shown in Fig. 2. The platform plate is formed at each end into a perpendicular flange 19 and 19' merging into outwardly projecting extensions 20 and 20 of different lengths. The

shorterflange extension 20 engages the angular projection Z1 positioned on the end wall'3 of the back member. The

longer iiange extension 20 is positioned to enter the space Y Thereuponv the shorter flange extension 20 is positioned to slide under the angular projection 21 of the end wall 3 and the inner channel unit is then moved in the opposite direction longitudinally of the back until the shorter flange extension is securely seated under the angular projection 21 to removably attach the inner channel member to the back member firmly at both ends. At the `same time the respective apertures 17 of the inner channel and 9 of the back member are brought into alignment. A rod 22 may then be passed through the respective apertures so that the back and inner channel members of the binder are securely locked against accidental movement in any direction.

The binder is adapted to pivot on the rod and is especially designed for use with my improved book stand. l. The projecting ledge 8 provides a finger grip to facilitate,l

or pamphlets in-the binder, there is removably mounted overtheplatforrnplate15.anl auxiliarypost-carryingunit 23 comprising two reciprocatingly operating angular metal plates 24 and 24 preferably of polished stainless steel. As-shown in Figs. 4 and 5 the baseplate 24 is'provided at .each endtwitha folded back return 2'6-and 265 forming an outwardly'projecting guideway or slide toreceive and Yretainthe complementaryplate 24"-in its-reciprocating action, and to prevent longitudinal movement of the two plates with; respect to each other when the post-carrying unit is un couplcd from the binder proper` Formed along one side of the base plate 24 is a perpendicular flange 27 on which is mounted a series of not less than two metal posts 25.A The lcomplementary plate 24' vis llikewise provided with a perpendicular sdeilange 2,7-having not-less than vtwo posts `25f 7rnounted"in staggered arrangement with respect to the opposite posts 25of the base'v plate 24; The perpendicular side yflanges of the respective plates areV formed at each end with inwardlyj projecting right angle extensions 2t?,A `and 28 merging into'rightnangled secondary longitudinal exten sions 29 and 29,' with notches or perforations 30 therein adapted to be positioned in the slotsl 6 and 6 in the cylinders and 5 of the back plate 1 vand retained thereinby the respective U-shaped wires 7 and 7.

In operation, the loose leaves 31 Figure 2 or other materialfto be'entered inv the binder are prepared with perforations along their inner margins to correspond with theuspacingof the respective'sets of binding posts. For example, the drawings show a total of four posts, one pair positioned on each of the plates 24 and 24' in staggered arrangement andthe material would therefore be provided withA four similarly spaced perforations' to enable allfour posts to enter therein simultaneously. The perforated material is then mounted'on one set of two post s 25 attachedtQ- thebase plate 24.

"The complementary plate24 islthen'v positioned on the under .side of and with its ends entered in the guideways 26 and 26 of theA base plate 24. The two plates are thenbrought together to a fully closed telescoping arrangement with the remaining two posts 25' projected intothe corresponding vacant perforations. The postcarryingunit its contents is thereupon coupled to the abovel described binder proper in -the following manner:

The post-carrying unit 23 i's positioned upon the platform plate 15 and nioved longitudinally of the platform plate sothatthe secondaryfnotched extensions-29', at oiie'endwill be proieeted` i nto the slots 6 'of the cylinder Sfso thetthewire vwill enter the notches'30. Thereupon the vwire 7 atthepopp'osite end fof lthe platform plate isv .with d rawn fromwthefcylinder 5 to `thelimit of Yits movement permitting the opposite notched extensions 29 torbe entered in the cylinderslots 6. The wire 7 is then retprned `to its normaliy closed position whereby the postpartying `un it vvith' its contents/is securely coupled to' thel binder proper in (Stile/rative`engagement To remove t he po st carrying Yunit and its contents from `the binderproper the operation is the reverse of the coupling mannerdescribed. V A

It is, to be noted that in the post-carrying unit above deseribedthe respective platesrareeach provided with a rninirnumof twosolid binding posts positioned in staggered arrangement In ,the case of perforated loose lehzvesriffit is"desired to'removeor insert new sheetsV at any given int ermed i ate 'positien in 4an alphabetical or' numerical, arrangementthe post-carrying unit is first ncgpledfrom 'thlindrmrpsr and the Contents Sen arated at the given point. Thereupon theplates areseparated with one portion of the contents being carried Y by the two posts of the base plate and the balance ofthe The device is thus provided with means to readily couplerthe pest-carrying, unit to the bindr.pr9ae r and to enable the loose leaves or other material contained therein to be rotated about a pivot without disengagement or damage thereto, and to readily uncouple the said unit for the purpose of alterations or additions to its contents.

A modification of the structure of the post-carrying unit is illustrated in Figures 6 and 7v of the drawings wherein the binding posts comprise two members, one of which consists of a solid metal post 32adapted to enter a complementary tubular post or sleeve 33 in telescopic arrafngement so that the solid post may be reciprocatingly operated therein. A series of not'vless than' two solid metal posts 32 are mounted as shown on the perpendicular flange of an annularmember 34, and a series of tubular metal posts 33 are mounted in exactly opposite arrangement on the complementary angular member 34. The perpendicular flanges of the respective angular members are formed at each end withl inwardly projecting extensions 35W-merging intoV secondary extensions 36. having notches or perforations 37 forcoupling the post-carrying unit to the binder proper exactly in the manner previously. described.

As shown in Fig. 7, lthe base or horizontal flanges of the respective angular members 34V and 34 are formed at each end with inwardlyprojecting extensions 38 for' the purpose of reinforcing thel extensions 35 of the perpendicular lianges to which the former are attached.

Inthe modified structure the angular'post-carrying members 34- and 34 by reason of the telescopingfeature of the binding posts mounted thereon are prevented from longitudinal movement withrespect to eachother when the post-carrying unit is uncoupled from the binder proper and the necessity for the telescoping feature of the plates themselvesV in the structure previously described is.thus eliminated and the number of telescoping binding posts and sheet perforations may be reduced to a minimum of two as compared to a minimum of four solid posts and sheet perforations in the previously described structure.

Inasmuchas this binder is especially adapted for publicuse in the display of data` in loose-leaf form which is frequently referred to, ithas been so designed as to permit of -re'ady replacementV of damaged 'parts in the field.A It is .to be noted that the' major elements of the binder proper are locked together in operative engagement by a removable 'rod 22. Upon removal of this rod these elements may be readily-disassembled by handwfor servicing in the-eld The auxiliary loose-leaf binding' element mayY likewise be readily disengage fromthe de vice for repair, upkeep or replacement. t

While'lhave' illustrated and describedwhat I .believe to be the preferred embodiment of my invention, it is obvious that'changes may be made in the generaly forni and arrangement ofthe parts without departing from'the spirit of the invention; hence I consider myself. at`lib'erty'to:make'snchchanges'and alterations as fairly` fall within thescope yof'the claims.

l. In a loose leaf binder the combination ofv a back plate formed with perpendicular end walls terminating in' slotted cylindrical coupling means adapted to receive a loose leaf element, and side walls having side covers hingedly attached thereto andi aligned aperturesV therein intermediate the ends-, an inner platform channel plate nested in s'i'lethebaclr'plate and having `similarly aligned side wall apertures, a 'removable ro'd passing through the are securely coupled thereto for movement without dislodgment.

2. A device in accordance with claim 1 in which the binding post carrying element comprises a pair of reciprocatingly operative flat metal base plates each having a perpendicular ange along one side extending beyond the base plate and terminating at each end in an angular extension having a notch therein, the said notched extensions being spaced apart and adapted to enter the said slots in the end cylinders of the back plate and secured therein by movable internal pins, the said side anges each having a minimum of two inwardly projecting binding posts mounted therein in alignment with and spaced apart in staggered arrangement relative to the opposite posts and having a plurality of loose leaves impaled thereon whereby when the binding post element is mounted on the said platform plate with the notched extensions locked in the cylinder slots the respective plates are prevented from lateral movement away from each other and the loose leaves are securely coupled to the binder.

3. A device in accordance with claim 2 in which one of the pair of reciprocatingly operative base plates of the binding post carrying element is formed at both ends with a bent back flange adapted to engage the at ends of the complementary plate and to form a guide for the reciprocal telescoping manipulation of the respective plates toward and away from each other, so that when the post carrying element is detached from the binder the plates are enabled to be freely moved laterally but are restricted in their relative longitudinal movement whereby the separation, alteration and reassembly of the leaves is greatly facilitated.
